rIOOL FOR NSERTING SPRINGS IN EYEGLASSES.

To @ZZ 107mm t may Concern.'

Be it known that I, AUGUSTUS R. Fnis'rnL, a citizen of the United States, and resident ofYork, in the county of York and State of Pennsylvania, have invented certain new and useful improvements in Tools for Inserting Springs in Eyeglasses, of which the following is a specification.

My invention is an improvement in tools for inserting springs in eye glasses, and the invention has for its object to provide a tool of the character specified, for placing the spring wire of the character used in the springs of eye glasses of the Shur-on type, wherein a holder is provided for supporting a reel of the wire, and having means for feeding the wire, and wherein a cutter is mounted o-n the holder for cutting the wire, arranged to be normally held in inoperative position, and to be moved into operative position and operated to cut by the same moving means, to permitthe insertion of the spring with one hand, leaving the other hand free to hold the glasses.

Inthe drawing: Figure 1 is a perspective view of the tool in use; Fig. 2 is a side view with parts in section; Figs. 8 and 4 are sections on the lines 3-3 and t-fl, respectively. of Fig. 2, each looking in the direction of the arrows adjacent to the line, and Fig. 5 is a perspective view of the sliding support for the cutting tool.

The present embodiment of the invention comprises a hollow, cylindrical casing 1, having at one end an externally reduced lip 2, for engagement byva cover 3, the cover having an annular rib 4 for convenience in handling the same, and being internally rabbeted as shown at 5 to engage the lip 2.

At the opposite end the holder has a reduced extension G having a central bore 7 communicating with the interior of the body of the holder, and a guide nozzle 8 is connected withV the outer end of the extension. The bore 7 of the extension is enlarged at the outer end as shown at 9, and the nozzle 8 has a cylindrical stem 10 which fits within the enlargement, and a rib 11 between the stem and the body of the nozzle engages the end of the extension to limit the inward movement of the nozzle.

A reel 12 is mounted in the body of the holder near the cap or cover 3, the saidreel having journal pins 13 which are j ournaled inthe wall of the holder at diametrically opposite points, and one of the journal pins Specification of Letters Patent.

has an axial opening polygonal in cross section for receiving a key to permit the reel to be rotated when placing the wire thereon.

The reel has a diametrical opening 1.4L for receiving one end of the wire 13, and the wire is passed downward through the bore 7 of the extension and through the opening of the nozzle, shown in Figs. 2 and 3. To mount the wire, it is threaded through the nozzle and the bore 7 of the extension,

and passed out at the open end of the body of the holder, the cap or cover 3 being re moved for this purpose. The inner end of the wire is then passed through the opening let, as shown in Fig. 3, and the reel is rotated to wind up the wire, until only a short portion of the wire is left extending through the nozzle. rlhis extended end of the wire is formed into a hook 16, as shown in Fig. 3, for a purpose to be presently set forth.

A cutter is mounted on the extension, the said cutter being connected with the Support shown in Fig. This support is a sleeve 17 having at its inner end a. marginal rib 18, the sleeve being of a size to iit over the extension, and the sleeve has a polygonal portion 19 intermediate of its ends, this portion 19 being square in cross section in the present instance.

TheI sleeve is longitudinally slotted, as shown at 20, at one side, and a set screw 21 Vis passed through the slot and into engage ment with the threaded opening in the extension, the slot limiting the movement of the sleeve with respect to the extension in both directions.

A coil tension spring 22 encrcles the extension between the sleeve and the body of the holder, and this spring is connected at its ends to the extension and to the sleeve. One end of the spring is bent around the sleeve on the outer side of the rib 1S, and the other end of the spring is bent around an annular rib 23 at the junction of the eX- tension with the body of the holder.

rlhe spring normally draws or urges the sleeve upward in the position of Figs. 2 and 3, that is, with the set screw 21 at the outer end of the slot 20. A fixed or ledger blade 24; is secured to the polygonal enlargement 19, the said blade having a shank 25 which at its upper end fits against one face of the enlargement, and is secured thereto in a manner to be described.

The movable blade 26 has a shank 27 and the said blade is pivoted to the fixed blade at the junction of the blades with their Shanks, by means of a Screw QS, in such manner that the movable blade may swing freely on the fixed blade.

A lever 29 is pivoted to the polygonal enlargement 19, by means of a screw 80, the said screw passing through the lever, the shank 25 of the fixed blade, and engaging a threaded opening in the sleeve. Thus the screw 30 pivotally connects the lever to the sleeve, and also connects the fixed blade to the sleeve.

The lever has a thumb piece or key 31 at its upper end for engagement bythe thumb of the user, and the lever has a notch or re cess 32 in its lower end, which engages the rounded end of the shank 2T of' the movable blade. ,p A coil spring 33 is bent around the screw 30, and one end of' the spring is hooked over the lever 29, the other end being fixed to the screw, and the spring acts normally to hold the parts in the position of' Fig. E2, that is, with the movable blade away from the ixed blade. I

The lever 29 is limited in its swinging movement by means of a pin 3i extending laterally from the shank of the fixed blade, and engaging an arc-shaped slot 35 in the lever. The pin and spring 33 normally hold the lever in the position of Fig. 2, and it will be evident that when the upper end of the lever 29 is swung in the direction of the arrow in Fig. 1, the movable blace will be swung with its cutting edge past the fixed blade to sever the wire when it is between said blades.

The sleeve and the mechanism which is carried thereby may be moved toward the free end of the nozzle by the lever 29, and the movable blade may be swung past the fixed blade to cut the wire by the same lever. The spring 32 will return the sleeve to normal position, and the spring 3B will return the lever to normal position.y

One oit' the journal pins 13 of the reel is a screw, as shown in Fig. el, so arranged that it may be removed, to permit the removal of the reel when it is necessary for any purpose. The nozzle 8 is also made detachable in order that it may be replaced 1n case of injury or in case it should become worn. The cover 3 gives access to the reel and to the wire thereon.

Each of the springs to be inserted in the eye glasses is seated on a screw 3G on the frame 3'? of the eye glasses, and one of the ends of the coil is vengaged with a guard arm on the nose piece, while the other end of the spring engages that portion of the frame which is connected with the lens 38, and the spring normally presses the guards toward each other, to clamp the glasses on the nose of the wearer.

The operation of the device will be evident from an inspection of Fig. 1, wherein the operation of inserting the spring is shown as almost complete. The hook 16 is enga ged with the guard arm on the nose piece. after which the wire is bent around the screw 36, three turns as a rule being required. When the hook 16 is hooked over the guard arm on the nose piece, the wire will be withdrawn from the reel as it is wrapped around the screw 36. After the coil has been formed, a trifle more of' the wire is withdrawn from the reel, enough to lap upon that portion of' the frame which is connected with the lens, after which with his thumb, the operator presses the sleeve 22 toward the point of' the nozzle. As soon as the wire is between the blades 24 and 26 the operator swings the lever 29 with the thumb, clipping the wire and leaving the spring in place.

But a single hand is required to manipus late the tool, the operator grasping the body of the holder in his hand, with the thumb on the thumb piece 31. A slight pressure oi the thumb will force the sleeve to the end of the nozzle, and a slight swinging motion ot' the thumb will sever the wire. p

The nozzle and holder provide for a firm grip ol' the wire during the placing of' the spring, and the passing of the wire through the nozzle insures that itwill be free from kinks, bends and the like. Furthermore, none of the wire is wasted. During the act of placing the spring, the spring is formed from the wire, each spring being formed as it is inserted.
